Have you wondered how information from physical devices in the real world gets communicated to Smartphone processors? Do you want to make informed design decisions about sampling frequencies and bit-width requirements for various kinds of sensors? Do you want to gain expertise to affect the real world with actuators such as stepper motors, LEDs and generate notifications?
In this course, you will learn to interface common sensors and actuators to the DragonBoard™ 410c hardware. You will then develop software to acquire sensory data, process the data and actuate stepper motors, LEDs, etc. for use in mobile-enabled products. Along the way, you’ll learn to apply both analog-to-digital and digital-to-analog conversion concepts.
Learning Goals: After completing this course, you will be able to:
1. Estimate sampling frequency and bit-width required for different sensors.
2. Program GPIOs (general purpose input/output pins) to enable communication between the DragonBoard 410c and common sensors.
3. Write data acquisition code for sensors such as passive and active infrared (IR) sensors, microphones, cameras, GPS, accelerometers, ultrasonic sensors, etc.
4. Write applications that process sensor data and take specific actions, such as stepper motors, LED matrices for digital signage and gaming, etc.

Infrared Sensors

Using sensors that work on the infrared spectrum we can send and receive information. With this knowledge we are ready to program/build a way to use this to our benefit. In this Module you will gain access to code that will allow you take tremendous steps forward in your pursuit to claim of piece of the IoT movement. We are also going talk about the infrared spectrum on a higher level to gain a better understanding of how we are able to use it for these projects. By the end of this Module, you will be able to take a household remote and control various aspects of your DragonBoard™ 410c, especially peripherals through GPIO manipulation.
